Detailed ways

The following are preferred embodiments of the application. It should be pointed out that for those skilled in the art, without departing from the principle of the application, some improvements and modifications can also be made, and these improvements and modifications are also considered as the present invention. The scope of protection applied for.

Before introducing the technical solution of the present application, the technical problems in the related art will be introduced in detail.

With the continuous development of science and technology, there are more and more types and quantities of electronic devices, which are now popular among users. For example, current electronic devices include mobile electronic devices, such as mobile phones and tablets. Or stationary electronic equipment such as desktop computers. Or wearable electronic devices, such as smart watches, etc. Head-mounted electronic devices such as AR glasses, VR glasses, etc. The head-mounted electronic device can implement technologies such as virtual reality or augmented reality, which brings various functions and good user experience to users.

However, the power consumption of electronic equipment is large, and it will inevitably generate a large amount of heat during operation, which makes the electronic equipment prone to heat and affects the performance and service life of the electronic equipment. Therefore, a fan is usually added in the electronic device at present, and the heat in the electronic device is discharged by using the rotation of the fan to achieve the purpose of heat dissipation. However, the current heat dissipation method is usually to control the fan to rotate at a fixed speed. Although such a heat dissipation method can achieve the purpose of heat dissipation, its heat dissipation effect is not ideal. When the speed of the fan is too high, a lot of power consumption will be wasted, and the noise will increase at the same time, which will reduce the battery life and service life of the electronic equipment. But if the speed of the fan is too low, the required cooling effect will not be achieved. Therefore, there is an urgent need to seek a new method for adjusting the fan.

In view of this, in order to solve the above problems, the present application provides a new fan adjustment method. Please refer to FIG. 1-FIG. 3 together. FIG. 1 is a schematic flowchart of an adjustment method in an embodiment of the present application. FIG. 2 is a schematic diagram of a three-dimensional structure of an electronic device in an embodiment of the present application. FIG. 3 is a schematic diagram along the direction A-A in FIG. 2 . This embodiment provides an adjustment method of the fan 20 , the adjustment method is applied to the electronic device 1 , and the electronic device 1 includes the fan 20 . Wherein, the adjustment method includes S100, S200, S300. Among them, the detailed introduction of S100, S200 and S300 is as follows.

S100. Determine a first rotational speed corresponding to the application program, and control the fan 20 to rotate at the first rotational speed.

The electronic equipment 1 that this application introduces includes but not limited to mobile phone, tablet computer, notebook computer, palmtop computer, personal computer (Personal Computer, PC), personal digital assistant (Personal Digital Assistant, PDA), portable media player (Portable Media Player) , PMP), navigation devices, wearable devices, head-mounted devices, smart bracelets, pedometers and other mobile terminals, as well as fixed terminals such as digital TVs and desktop computers. Optionally, the head-mounted electronic device 1 includes a see-through type and a see-closed type. The see-through type provides augmented reality (Augmented Reality, AR), while the closed type provides virtual reality (Virtual Reality, VR). It can also be understood that the head-mounted electronic device 1 includes AR glasses or VR glasses. Further optionally, in the following text of this application, the electronic device 1 is used as AR glasses for illustration. As for the specific structure of the electronic device 1 , this application will introduce in detail later.

When a user uses the electronic device 1 , various functions are realized by running various application programs stored in the electronic device 1 . For example, the application program includes a chat program, a game program, a video program, a picture program, or other application programs. When the electronic device 1 runs the application program, the first rotational speed corresponding to the application program is determined. The first rotational speed here can be understood as the rotational speed of the fan 20 required to dissipate heat when the application program is running. After obtaining the first rotational speed, the fan 20 can be controlled to rotate and dissipate heat at the first rotational speed. The above content can also be understood as, as soon as the electronic device 1 runs the application program, it can start to control the rotation of the fan 20 to perform heat dissipation treatment, so that the heat dissipation can be intervened earlier, so that the heat dissipation effect of the electronic device 1 can be improved, and the heat dissipation in the electronic device 1 can be protected. Various structural parts improve the service life of the electronic equipment 1 .

In addition, in this implementation manner, the first rotational speed corresponding to the application program may be determined in various manners. For example, optionally, the first rotational speed corresponding to the application program may be determined according to parameters of the application program. Wherein, the parameters of the application program may include one or more of the type of the application program, the power consumption of the application program, and the number of the application program. For example, when the parameter of the application program is the type of the application program, it can be called from the information pre-stored in the storage module when the electronic device 1 runs the application program. Or when the application program is running, the type of the application program is obtained from the network in real time, and finally the type of the application program can be obtained. When the parameter of the application program is the power consumption of the application program, the power consumption of the application program may be obtained when the electronic device 1 runs the application program. The power consumption here may be initial power consumption or real-time power consumption. When the parameter of the application is the number of applications, for example, the electronic device 1 runs two applications, one of which is the application being used by the user, and the other is running synchronously in the background, at this time, the running The total number of applications. In addition, after the parameters of the application program are obtained, the first rotational speed can be determined according to the parameters.

For example, when the type of the application program is chat software, it can be determined that the first rotation speed can be 500r/min; when the type of the application program is game software, it can be determined that the first rotation speed can be 1000r/min. For example, when the power consumption of the application program is 100w, it can be determined that the first rotation speed can be 500r/min; for example, when the power consumption of the application program is 200w, it can be determined that the first rotation speed can be 1000r/min. For example, when the number of application programs is 1, it may be determined that the first rotational speed may be 500 r/min. When the number of applications is 2, it can be determined that the first rotational speed can be 1000 r/min.

S200. Acquire environmental parameters of the electronic device 1, and determine a second rotational speed corresponding to the application program according to the environmental parameters.

After the fan 20 rotates at the first rotational speed to dissipate heat for the electronic device 1 , although the purpose of dissipating heat is achieved. However, when the fan 20 rotates at the first rotational speed, noise will be generated accordingly. If the first rotational speed is too high, a large amount of power consumption will be wasted and the battery life of the electronic device 1 will be reduced. And the noise it generates is too large, which will also affect the user experience. However, if the first rotating speed is too small, the ideal cooling effect cannot be achieved.

Therefore, in this embodiment, the environmental parameters of the electronic device 1 can be obtained first. Wherein, the environmental parameters referred to in this embodiment include at least one of internal environmental parameters and external environmental parameters of the electronic device 1 . For example, the internal environment parameters may include the volume that is indirectly produced by the application when it is run. The external environment parameter may include at least one of external noise volume and external environment brightness. Then the second rotational speed corresponding to the application program can be determined according to the environmental parameters. The second rotational speed here does not mean that the follow-up fan 20 should rotate at the second rotational speed. The function of the second rotational speed is to compare with the first rotational speed, and then control the rotational speed of the fan according to the result of the comparison. . Or it can also be understood that the second rotational speed is the maximum rotational speed limit of the fan 20, and the maximum rotational speed of the fan 20 cannot exceed the second rotational speed, rather than that the rotational speed of the fan 20 must be the second rotational speed.

S300. Control the fan 20 to rotate at a target speed according to the first speed and the second speed; wherein, the target speed is the first speed or the second speed, or the target speed is at the between the first rotational speed and the second rotational speed.

When obtaining the second rotational speed, the fan 20 is still rotating at the first rotational speed. Then, the fan 20 can be controlled to rotate at the target speed according to the first speed and the second speed. In this way, after running the application program, the shell adjusts the speed of the fan 20 in real time according to the environmental parameters. On the premise of ensuring the heat dissipation performance, it not only reduces the comprehensive power consumption of the electronic device 1, but also improves the balance between heat dissipation and noise. The overall performance of the electronic device 1 is improved. For example, when the user is in a quiet environment, the rotation speed of the fan 20 can be appropriately reduced to reduce the impact of noise on the user while dissipating heat. When the user is in a noisy environment, the user is mainly affected by environmental noise, and the noise of the fan 20 will not affect the user, so the speed of the fan 20 can be appropriately increased.

As for the specific size of the target speed, whether the target speed is the first speed or the second speed, or whether the target speed is between the first speed and the second speed can be comprehensively considered according to the magnitude of the first speed and the second speed. This application will be described in detail below.

To sum up, the adjustment method provided by this embodiment enables the heat dissipation process to be performed when the application program is just started to run, thereby improving the heat dissipation effect. And the speed of the fan 20 is adjusted in real time according to the environmental parameters, which not only reduces power consumption, but also improves the balance between heat dissipation and noise.

Next, the present application provides two specific implementations of "controlling the fan 20 to rotate at a target speed according to the first speed and the second speed" according to the magnitudes of the first speed and the second speed. The details are as follows:

Please refer to FIG. 4 together. FIG. 4 is a schematic flowchart of S400 in an embodiment of the present application. In this embodiment, S300 "control the fan 20 to rotate at a target speed according to the first speed and the second speed" includes S310 and S320. Among them, the details of S310 and S320 are as follows.

S310. Determine the magnitudes of the first rotational speed and the second rotational speed.

S320. If the first rotational speed is greater than the second rotational speed, control the target rotational speed to be the second rotational speed.

In the first implementation manner, when the first rotational speed is greater than the second rotational speed, that is, the second rotational speed obtained according to the environmental parameter is smaller than the second rotational speed obtained according to the application type. For example, the first rotation speed is 1000r/min, and the second rotation speed is 500r/min. At this time, the target rotational speed can be controlled to be the second rotational speed, that is, the fan 20 can be controlled from 1000 r/min to 500 r/min. However, this application does not limit how the speed of the fan 20 changes from 1000r/min to 500r/min, for example, it can be reduced to 500r/min instantaneously, or slowly reduced to 500r/min within a certain period of time. In this way, when the user is in a relatively quiet environment, the noise of the fan 20 can be reduced while ensuring the heat dissipation of the fan 20 to achieve optimal overall performance.

Please refer to FIG. 5 together. FIG. 5 is a schematic flowchart of S400 in another implementation manner of the present application. In this embodiment, S300 "control the fan 20 to rotate at a target speed according to the first speed and the second speed" includes S330 and S340. Among them, the details of S330 and S340 are as follows.

S330. Determine magnitudes of the first rotational speed and the second rotational speed.

S340. If the first rotational speed is less than the second rotational speed, control the target rotational speed to be the first rotational speed; or control the target rotational speed to be greater than the first rotational speed and less than or equal to the second rotational speed.

In the second implementation manner, when the first rotational speed is lower than the second rotational speed, that is, the second rotational speed obtained according to the environmental parameter is greater than the second rotational speed obtained according to the application type. For example, the first rotation speed is 500r/min, and the second rotation speed is 1000r/min. This embodiment provides two control methods. In the first control method, since the fan 20 maintains the first speed to meet the purpose of heat dissipation when the application program is in use, the speed of the fan 20 can be kept constant, which is still the first speed, that is, the target speed is controlled is the first rotational speed. In the second control method, since the first rotational speed has not yet reached the limit value of the maximum rotational speed (i.e. the second rotational speed), and even the second rotational speed can meet the requirements for environmental parameters, the rotational speed of the fan 20 can be increased, as long as greater than the first rotational speed, and at the limit value of the maximum rotational speed (i.e. the second rotational speed); that is, to control the target rotational speed to be greater than the first rotational speed and less than or equal to the second rotational speed, so that the noise can be satisfied Under the premise of affecting the user, the speed of the fan 20 is increased as much as possible, so as to improve the heat dissipation performance of the fan 20 .

As for how much to increase the rotation speed, the present application does not make a limitation here, and it can be determined according to actual conditions.

Next, this application will continue to introduce how to determine the second rotational speed corresponding to the application according to the environmental parameters. The present application provides two specific implementation manners according to types of environment parameters. The details are as follows:

Please refer to FIG. 6 together. FIG. 6 is a schematic flowchart of S300 in an embodiment of the present application. In this embodiment, S200 "acquire the environmental parameters of the electronic device 1, and determine the second rotational speed corresponding to the application program according to the environmental parameters" includes S210 and S220. Among them, the details of S210 and S220 are as follows.

S210. Acquire environmental parameters of the electronic device 1; wherein the environmental parameters include at least one of a volume when the application program is running and a volume of external noise.

S220, when the environment parameter includes the volume when the application is running, and the volume when the application is running is greater than the preset volume; or, when the environment parameter includes the volume when the application is running and the volume of the external noise, and the volume when the application is running is greater than the volume of the external noise, and when the volume of the application is running is greater than the preset volume, according to the volume when the application is running Determine a second rotational speed corresponding to the application program; wherein, the second rotational speed is greater than or equal to the first rotational speed.

In a first implementation manner, the environment parameter includes at least one of the volume of the application program running and the volume of external noise. It can be seen from the above content that the volume of the running application program can be regarded as an environmental parameter in the electronic device 1 . Wherein, the volume when the application program is running can be understood as, when the application program is running, for example, when the user is watching a video, listening to music or playing a game, the processor 30 can receive the audio signal sent by the application program, and then control the volume according to the audio signal. The volume formed by the speaker in the electronic device 1 producing sound. In addition, the processor 30 can obtain the volume of the running application program according to the audio signal.

The external noise volume can be regarded as an environmental parameter outside the electronic device 1 . For example, when the user is in a noisy environment, there will be various sounds in the external environment, and these sounds will affect the user's experience when using the electronic device 1 , so they can be collectively referred to as external noise volume. In addition, a sound sensor, such as a MIC, can be added to the electronic device 1 to detect the volume of external noise.

When the environmental parameters include the volume of the application program running, it can be understood that the user is in a relatively quiet external environment and is using the electronic device 1 to watch videos, listen to music or play games. At this time, when the volume of the application program is running is greater than the preset volume, that is, when the volume of the application program is running sufficiently, it can be considered that the noise generated by the fan 20 will not affect the user watching videos or playing games. Therefore, there is no need to adjust the rotation speed of the fan 20 at this time, so that the second rotation speed can be greater than or equal to the first rotation speed.

When the environmental parameters include the volume when the application program is running and the volume of the external noise, that is, include internal environmental parameters and external environmental parameters, it can also be understood that the user is watching videos, listening to music or playing games in a noisy external environment. However, when the volume of the application program is running is greater than the volume of the external noise, and the volume of the application program is running is greater than the preset volume, that is, the volume of the application program is running is large enough, not only greater than the preset volume, It is also greater than the noise of the external environment. At this time, it can also be considered that the noise generated by the fan 20 will not affect the user watching videos or playing games. Therefore, there is no need to adjust the rotation speed of the fan 20 at this time, so that the second rotation speed can be greater than or equal to the first rotation speed.

To sum up, in this embodiment, when the volume of the application program is running is high enough, the rotation speed of the fan 20 can be increased, so as to ensure the balance between heat dissipation and noise, and achieve an optimal heat dissipation effect. As for the volume of the external noise and the preset volume, this embodiment does not limit it here.

Optionally, the preset volume is greater than or equal to 100dB.

Please refer to FIG. 7 together. FIG. 7 is a schematic flowchart of S300 in another implementation manner of the present application. In this embodiment, S200 "acquire the environmental parameters of the electronic device 1, and determine the second rotational speed corresponding to the application program according to the environmental parameters" includes S230 and S240. Among them, the details of S230 and S240 are as follows.

S230. Acquire environmental parameters of the electronic device 1; wherein the environmental parameters include at least one of volume when the application program is running, external noise volume, and external environment brightness.

S240, when the environmental parameters include the volume of the application program running and the volume of the external noise, and the volume of the application program running is less than the volume of the external noise, and the volume of the external noise is less than a preset When volume is used, a second rotational speed corresponding to the application program is determined according to the external noise volume; wherein, the second rotational speed is smaller than the first rotational speed.

Or, when the environment parameters include the volume of the application program running, the volume of the external noise, and the brightness of the external environment, and the volume of the application program running is smaller than the volume of the external noise, the When the volume of the external noise is less than the preset volume and the brightness of the external environment is lower than the preset brightness, the second rotational speed corresponding to the application program is determined according to the volume of the external noise and the brightness of the external environment; wherein, the second The second rotational speed is smaller than the first rotational speed.

In a second implementation manner, the environment parameter includes at least one of volume when the application program is running, volume of external noise, and brightness of the external environment. In other words, the internal environment parameter is still the volume when the application program is running, and the external environment parameter may include the brightness of the external environment in addition to the external noise volume. In addition, the processor 30 can obtain the volume of the running application program according to the audio signal. A sound sensor, such as a MIC, can also be added to the electronic device 1 to detect the volume of external noise. A brightness sensor, such as a light sensor, may also be added to the electronic device 1 to detect the brightness of the external environment.

When the environmental parameters include the volume of the application program being run and the volume of external noise, that is, including internal environmental parameters and external environmental parameters, and the volume of the application program is running is smaller than the volume of the external noise, and the volume of the external noise is less than When preset volume. It can also be understood that when the user is running the application, the application has no volume, for example, the user watches pictures, or watches videos, listens to music or plays games in mute. Or, its apps run at a lower volume. Or the external noise is too loud, so that the volume of the application program being run is smaller than the external noise volume, and the external noise volume is smaller than the preset volume. Generally speaking, the user is in a relatively quiet state. At this time, it can be considered that the noise generated when the fan 20 rotates at the first speed will be captured by the user and affect the user experience. Therefore, the second speed can be lower than the first speed. , and the subsequent control target speed is the second speed.

When the environmental parameters include the volume when the application program is running, the volume of the external noise, and the brightness of the external environment, it includes internal environmental parameters and external environmental parameters. It can be understood that when the user is running the application, the application has no volume, for example, the user looks at pictures, or watches videos, listens to music or plays games in mute. Or, its apps run at a lower volume. Or the external noise is too loud, so that the volume of the application program is smaller than the external noise volume, and the external noise volume is smaller than the preset volume, and the external environment brightness is smaller than the preset brightness. Generally speaking, the user is in a relatively quiet and dark environment. At this time, it can be considered that the noise generated when the fan 20 rotates at the first speed will be captured by the user and affect the user experience. Therefore, the second speed can be lower than the first speed. The first rotational speed, and the subsequent control target rotational speed is the second rotational speed.

To sum up, in this embodiment, when the volume of the application program is running and the volume of the external noise is too small, the size of the second rotational speed can be reduced, thereby reducing the rotational speed of the fan 20, and while losing part of the heat dissipation performance, the noise does not affect the user, ensuring The balance between heat dissipation and noise is achieved to achieve the best heat dissipation effect. As for the volume of the external noise and the preset volume, this embodiment does not limit it here.

Optionally, before "obtaining the environmental parameters of the electronic device 1, and determining the second rotational speed corresponding to the application program according to the environmental parameters", it may also include: obtaining the working state of the fan 20; when the When the fan 20 stops working, the environmental parameters of the electronic device 1 are obtained, and the second rotational speed corresponding to the application program is determined according to the environmental parameters. In some special cases, it needs to be considered that the fan 20 suddenly stops working for some reason when it is working normally. However, since the fan 20 rotated at the first rotational speed according to the type of the application program before, it is not necessary to repeat the above operation at this time, and the environmental parameters of the electronic device 1 can be obtained directly, and determined according to the environmental parameters. The second rotation speed corresponding to the program makes the fan 20 directly rotate in the second stage.

Optionally, the preset volume is less than or equal to 40dB. Optionally, the preset brightness is less than 5lux.

Please refer to FIG. 8 together. FIG. 8 is a schematic flowchart of S100 in an embodiment of the present application. In this embodiment, S100 "when the electronic device 1 runs the application program, determine the first rotation speed corresponding to the application program, and control the fan 20 to rotate at the first rotation speed" includes S110, S120, S130 . Among them, the details of S110, S120 and S130 are as follows.

S110. When the electronic device 1 runs an application program, obtain the first power consumption according to the type of the application program.

When the electronic device 1 starts to run the application program, the first rotation speed cannot be determined immediately. Instead, the first power consumption is obtained according to the type of the application program. Wherein, the types of application programs have been introduced in detail above, and will not be repeated here in this embodiment. The first power consumption can also be understood as preliminary power consumption, wherein the preliminary power consumption of each application program can be stored in advance, and then called from the storage module when the application program is running. Or obtain the preliminary power consumption of the application program from the network in real time when the application program is running.

Optionally, the default brightness of the screen may be obtained according to the type of the application program; and then the first power consumption may be obtained according to the default brightness of the screen.

S120. Acquire a brightness value of the display screen in the electronic device 1, and obtain a second power consumption according to the brightness value and the first power consumption.

When the application program is running, the brightness value of the display screen in the electronic device 1 can be obtained in real time, and then the second power consumption can be obtained according to the brightness value obtained in real time and the first power consumption. Wherein, the second power consumption may be regarded as accurate power consumption or real-time power consumption of the application program during the running process.

As for how to obtain the second power consumption according to the brightness value and the first power consumption, this application does not make a limitation here.

In addition, the first power consumption and the second power consumption mentioned above refer to the first power consumption and the second power consumption of the electronic device 1 when the application program is running. Optionally, the first power consumption and the second power consumption may be regarded as the temperature of the CPU in the electronic device 1 or the frequency of the CPU.

S130. Determine a first rotational speed corresponding to the application program according to the second power consumption.
